Technical Field

[0001] This utility model relates to an external microphone-type RIC hearing aid, belonging to the field of RIC hearing aid technology. Background Technology

[0002] Currently, the most common hearing aids on the market are body-worn, behind-the-ear, and custom-made. Due to intense market competition and higher customer demands, RIC hearing aids have gradually been introduced. These hearing aids are more discreet, compact, and aesthetically pleasing. They generally consist of a hearing aid unit and a receiver, which are connected by a conduit.

[0003] Existing receivers generally have mushroom-shaped tips and cerumen screens. The sound holes on the mushroom-shaped tips are axially aligned with the speaker on the receiver, so a cerumen screen is needed to prevent cerumen blockage. Cleaning the cerumen screen requires professional personnel to disassemble the receiver, which is costly. In addition, the existing hearing aid main unit is still relatively large, and its concealment effect when hanging behind the ear is poor, making it less aesthetically pleasing. To address the above shortcomings, this utility model proposes an external microphone-type RIC hearing aid. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an external microphone-type RIC hearing aid to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an external microphone type RIC hearing aid, the structure of which includes a receiver assembly, and a thin wire is electrically connected to the right side of the receiver assembly, and the other end of the thin wire is electrically connected to an external microphone, and an anti-blocking earplug is wrapped and fitted on the left side of the receiver assembly.

The external microphone device includes a first external shell and a second external shell, and the microphone body is fitted inside the cavity between the first external shell and the second external shell.

[0006] A further improvement is that a speaker slot is provided at the lower end of the cavity of the active housing, and a sleeve post is provided in the middle of the bottom surface of the active housing. A sound outlet channel is provided between the middle of the bottom surface of the sleeve post and the speaker slot. An organic core retaining edge is provided at the upper end of the cavity of the active housing. The right side of the top surface of the retractable cover has a button opening for the movement body to extend outward, and the left side of the top surface of the retractable cover has a first threading hole.

[0007] A further improvement is that the front side of the first outer shell is provided with multiple sound-receiving holes, and the top surface of the first outer shell is provided with a first retaining fin. The second outer shell cavity has a microphone body sleeve groove, and the bottom of the microphone body sleeve groove has a second wire hole. The top surface of the second outer shell is provided with a second fin that fits into the first fin.

[0008] A further improvement is that the anti-blocking earplug is made of silicone, the anti-blocking earplug is a conical cover, the lower end of the cavity of the anti-blocking earplug is provided with an elliptical groove that engages with the sleeve post, the bottom of the elliptical groove is provided with an anti-blocking sound passage groove, and the lower edge of the anti-blocking sound passage groove is provided with multiple small sound outlet holes in a circular array.

[0011] The beneficial effects of the utility model are: This utility model provides an external microphone-type RIC hearing aid. Through the structural combination design of a receiver assembly, a thin wire, an external microphone, and an anti-occlusion earplug, an external microphone-type RIC hearing aid is constructed. The wearing distance between the microphone body on the external microphone and the speaker on the receiver assembly can be lengthened, effectively reducing knocking during use. Since the external microphone has only one microphone body, its size can be minimized, improving its concealment behind the ear and making the wearing more aesthetically pleasing. The anti-occlusion earplug, by adding an anti-occlusion sound passage and having a non-axial design between the sound outlet and the speaker, can directly eliminate the need for a cerumen screen. When cleaning the cerumen, simply remove the anti-occlusion earplug for washing; there is no need to remove the receiver assembly, avoiding after-sales cleaning costs and demonstrating strong practicality.

An anti-blocking earplug 4 is wrapped and fitted on the left side of the receiver assembly 1. The receiver assembly 1 includes a receiver shell 11, and a core body 12 and a speaker 13 are fitted inside the cavity of the receiver shell 11. The top surface of the receiver shell 11 is covered with a receiver shell cover 14 to press and fix the core body 12 and the speaker 13. The external microphone 3 includes a first external shell 31 and a second external shell 32, and a microphone body 33 is fitted inside the cavity between the first external shell 31 and the second external shell 32.

[0015] The lower end of the cavity of the active housing 11 is provided with a speaker sleeve groove 111, and a sleeve post 112 is provided in the middle of the bottom surface of the active housing 11. A sound outlet channel 113 is provided between the middle of the bottom surface of the sleeve post 112 and the speaker sleeve groove 111. The upper end of the cavity of the active housing 11 is provided with a core retaining edge 114. The right side of the top surface of the active housing cover 14 is provided with a button opening 141 for the core body 12 to extend outward. The left side of the top surface of the active housing cover 14 is provided with a first wire hole 142.

[0016] The first outer shell 31 has a plurality of sound receiving holes 311 through the front side, and the top surface of the first outer shell 31 is provided with a first retaining fin 312. The cavity of the second outer shell 32 is provided with a microphone body sleeve groove 321, and the bottom of the microphone body sleeve groove 321 is provided with a second wire hole 322. The top surface of the second outer shell 32 is provided with a second retaining fin 323 that fits with the first retaining fin 312.

[0017] The anti-blocking earplug 4 is made of silicone and is a conical cover. The lower end of the cavity of the anti-blocking earplug 4 is provided with an elliptical groove 41 that engages with the sleeve post 112. The bottom of the elliptical groove 41 is provided with an anti-blocking sound passage groove 42, and the lower edge of the anti-blocking sound passage groove 42 is provided with multiple small sound outlet holes 43 in a circular array.

[0018] The main body 12 of the mechanism, the thin wire 2, and the microphone body 33 are electrically connected, and the main body 12 of the mechanism and the speaker 13 are electrically connected by contact.

[0019] Working principle: When wearing the earpiece, the anti-blocking earplug 4 and the receiver assembly 1 are first assembled and pushed into the ear canal. At this time, the anti-blocking earplug 4 can deform to completely seal the ear canal, while the sound outlet 43 will not abut against the ear canal wall, allowing sound to pass through unimpeded. Then, the microphone body 33 is hung behind the ear for concealment. (See attached diagram) Figure 1 Since the microphone component 3 consists of only one part, the microphone body 33, its size can be minimized. Furthermore, the microphone component 3 is designed with a first locking fin 312 and a second locking fin 323, which effectively improves the concealment and stability of the microphone component 3 when it is hung behind the ear.

[0020] When in use, external sound enters through multiple sound-receiving holes 311, is received by the microphone body 33, and is transmitted through the thin wire 2 to the main body 12 of the mechanism for reception, processing and amplification before being played out by the speaker 13. The sound is transmitted from the sound outlet 113 into the anti-blocking sound channel 42 and then out of the ear canal through multiple sound outlet holes 43.

[0021] In addition, during use, because the sound outlet 113 and the sound outlet hole 43 are designed to be offset, and the sound outlet hole 43 and the ear canal are not axial, the earwax can only block the outer hole of the sound outlet hole 43, and will not block the sound outlet 113 and the speaker 13 at all. Therefore, when cleaning the earwax on the anti-blocking earplug 4, you can simply remove it and wash it with water. The operation is simple and convenient.

[0022] In addition, the increased distance between the microphone body 33 and the speaker 13 can effectively reduce the occurrence of knockouts during use.
